  1. Great wiring guide! It will be my reference when I do my swap. :)

  2. What a weekend SOB!!!!

    I don't know what performance products idea of "honing" is but I think it will likely need to be machined, at least 10,000ths off. We tried a bit of emory paper to check for any burrs, etc, but without a proper micrometer to check the bore it was a no go. A crank pulley should slide on smoothy without resistance at least as far as the keyway, this was almost impossible to even get started on the crank nose. I'm pretty sure a compitant tig welder could fix the radiator with a quick zap, it wasn't that bad, but for Joe, the last thing he wanted to see was the radiator damaged. It just added to the stress level. Has anyone on here done the tauris fan on a race radiator? if so, what was your clearance on the shroud from the waterpump? I think next time, we'll do the wiring, since that has taken a back seat to the more mechanical things. I like the reply from PP, " a handful of pulleys may give difficulty"! Yeah, no kidding, I was hoping the pulley install would go smooth to help Joe feel better. I for one felt like a heel for nicking his radaitor. Chris Rummel
  3. Chris Rummel's easy follow RB into Z wireing guide

    If it is very radical changes to what has been posted, start a new thread if it is the same on the basic wiring etc, then just add the differences to the thread. Chris Rummel

    Figures, I just let my JP subscription run out last month! I guess I can buy it at the newstand. My mum in law used to get it for me for my b-day for the last couple of years. (cheaper because she lives in England) Will you give me props in the article for helping with the wiring? Chris Rummel
  5. Chris Rummel's easy follow RB into Z wireing guide

    Hi all, very happy to see people adding lots of useful information since I checked in last. This was my intention of this thread, so it would evolve as new info developed to be shared by this community and answer the questions that have come up since I originally posted this info. I'm very chuffed. Also a sad update, on the car that I did for my friend (the one in this thread) he had a bad bad cooling fan relay failure that consequently caught the rubber pad over the hots in front of the battery on fire and badly damaged the wiring in that area. Good thing he had a good neighbor that pulled the hood open and got the fire out with a minimum of damage. Bad news is that he had just got the car painted! Also it looks like it is fixable so his RBZ will live again. Once again cudos for additional info to help this thread evolve. Chris Rummel

    Sure, Like I said I want this thread to evolve and anything that makes this more clear should be added. You can never have too much information on something like this. As long as it is quality information that helps make the process more clear. Chris Rummel
  7. what ecu's work best

    Correct, we did get into the Wolf V500 early, in fact ours was probably one of the first ones shipped i'd wager, since they anounced it in November 06 and we recieved it in January 07. Yes back then it came with no map on it at all, good to hear that you can now get it with a base map, that is a huge step forward for them, now all they need to do is post a set of better instructions and perhaps a video for the timing verification and they will be set. The Wolf is a very powerful and flexable system, it has more features then we really needed or really wanted to set up. One of the main reasons we were interested in it in the first place is because it got rid of the MAF and had a built in MAP sensor, that you needed to pay extra for on the Power FC. For our purposes though, the power FC is more of what we were looking for in this application. If anybody is interested this V500 is for sale by owner and also has the Dash tuning display included with it. I'm sure you could get a good deal on it. Then you can contact Racinjitter and get a good base map for it. If anyone is interested shoot me a pm and check with the owner to see how much he wants for it. The power fc is really great, only two real problems with it, one its out of production now, and two is the time involved with tuning it using the commander. it also doesnt' have a lot of the features such as wideband tuning or auto tune etc that the more current systems have, but if you are interested in something to get you going easy and still get a good tune its great. If you are looking for a stand alone at a good price you can always look to the Mega squirt, it is a bit more DIY then most, but you can get a version that does every thing that the more expensive systems do for a very reasonable price.

  8. what ecu's work best

    We sourced the Apex i from our local tuner Mid atlantic motorsports, and yes they are getting expensive now that the no longer make them. The power fc is a full stand alone that plugs into the stock wiring harness in place of the stock ecu. Pretty much the easiest plug and play out there, with a good base map to get you going. It is a little dated, and with the basic fc you need to retain the MAF, but there is a version that lets you ditch the MAF. The other disadvantage of the basic one, is that you need to program using the commander and the thumb action required gets a bit tedious. The more advanced version is able to connect and tune via a laptop. Chris Rummel
  9. what ecu's work best

    I tried the Wolf V500 for the RBZ and didn't have any luck with it. I got the "plug and play" for the RB25DET and it was that in name only. It didn't come with any base map installed, and the only plug and play thing about it was the plug that plugs it into the stock wiring harness. I tried everything in my ability to get the timing varified (in sync with the engine) and gave up took it to our local RB expert tuner and he had the car for 4 months before he gave up trying to get the timing varified too. I had a lot of help from Ron Tyler including him emailing me a base map he got from Wolf. Ron Tyler is a fantastic guy to deal with so this is nothing negative against him, He did everything humanly possible to help me with this thing, but Wolf leaves a lot to be desired when it comes to support and instructions with this thing. When i buy something that is advertised as plug and play I expect it to be that, and include at the very least a base map for the car it is supposed to be pluging and playing with. They also need to have proper instructions either with the unit or a video online to show EXACTLY how to verifiy the timing, because unless you get past this step you cannot continue getting the car running. I would suggest that wolf takes a look at the MegaSquirt website (actually DIYautotune) as they have a very outstanding video posted online that walks you through step by step with getting the timing verified. In the end we pulled the wolf out, and replaced it with an Apexi Power FC and had no further problems, that thing is truly plug and play, it not only comes with an outstanding base map, (that instantly solved a mysterious idle problem i was having with the stock ecu ) but also has a year of weather programing built in so you don't really have to fiddle with cold start or any of that mess. My friends car with the apexi FC running the RB25DET dynoed at 302whp and runs flawlessly now. Chris Rummel

    Andy, that is an excellent addition to this thread, and exactly what I wanted to have happen with this. I want it to continue to evolve with any new additions that make the swap wiring either easier or as in this case more diverse applying to the RB26 as well as the RB25. These additions only make it easier and more clear for everybody. Outstanding and Cheers mate. Chris Rummel
  11. Chris Rummel's easy follow RB into Z wireing guide

    Andy I wish I could help you out there, but I don't recall seeing that on the RB25 harness, probably because the 25 uses high impedence injectors. I think I would have remembered seeing that. Maybe on of the guys that did the 26 would be more help with this question. try posting is as a seprate thread. Sorry Chris
  12. Chris Rummel's easy follow RB into Z wireing guide

    On the in car harness section all the Solid Black wires go to ground and are all connected. Just make sure they are all SOLID black not black with white stripe or anything like that. Going from the ecu pin out If you don't have the inside harness, find the ones that are listed as ground and wire them to go to ground. They are all interconnected anyway, so as long as they are listed from the ecu as ground or are solid black you can safely send them to ground or earth as they say in the UK I usually will run a ground wire from under one of the ecu case screws to ground as well to ground the ecu itself, since a lot of times in these swap cases, the ecu is held in place with zip ties or otherwise not well grounded. Hope this helped Andy. Chris Rummel
  13. Stock RB25det max boost?

    This turbo, makes really good usable power, it is not the biggest turbo out there, but it works really good on the street, with lots of meat under the curve. The guy that tuned it, said it was much nicer on the RB then anouther one he had in the shop with a larger turbo on it. Much easier to tune, and a lot more Usable power then a larger turbo, so a good match for the Rb for street use. You could probably get another 40hp or so out of it with larger injectors and more tuning. I believe this turbo is rated at about 350-370 max. Chris Rummel
  14. Stock RB25det max boost?

    The stock turbo is good to about 12psi before risking the exhaust blades. it is an T3 exhaust side with ceramic blades mated to a T28 compressor. I used a HKS GT2540 on my friends car it is basically a stock size turbo with larger guts and a steel exhaust impellor. good for a very usable 18psi up to probably 20psi, it is VERY responsive, starts building boost at around 2k rpm and pulls very strong all the way to redline. It is a direct replacement turbo on the stock RB25 manifold and makes a fantastic street turbo. my friends car that is internally stock but with a greddy intake and a 3 inch exhaust makes 305 rwhp at ~12psi with it. We got it off ebay japan it was just over a grand shipped and included a nice divorced wastegate upper down pipe. A good deal because just the turbo goes for a tick over 2k new and this one was in very good condition Under 10,000 klm on it. Chris Rummel
  15. Cometic head gasket

    I used one in the RBZ car and it works fine, they are made really well, at least as well as HKS, I'd be willing to say it will take anything you can throw at it. Chris Rummel
